Explanatory notes
1
This unit standard can be assessed against in a workplace environment, or in a
training or educational environment if simulated equipment response and examples
are able to be provided, or in a combination of both environments.
2
Performance and work practices in relation to the outcomes and evidence
requirements must comply with all current legislation, especially the Electricity Act
1992, and any regulations and codes of practice recognised under that statute; the
Health and Safety in Employment Act 1992; and the Resource Management Act
1991. Electricity supply industry codes of practice and documented industry
procedures include the Safety Manual – Electricity Industry (SM-EI) (Wellington:
Electricity Engineers’ Association, 2010). A full list of current legislation and industry
codes is available from the Electricity Supply Industry Training Organisation, PO Box
1245, Hamilton 3240.
